Defensive publication

ABSTRACT

A METHOD OF FORMING TRANSFERRED LIQUID DEVELOPED ELECTROSTATIC IMAGES INCLUDES THE STEOP OF FORMING AN ELECTROSTATIC CHARGE PATTERN ON A CHARGE-BEARING MEMBER, APPLYING TO SAID PATTERN A LIQUID DEVELOPER CONTAINING A MORDANTABLE, WATER-SOLUBLE ACID DYE SALT TO FORM A DEVELOPED IMAGE, SUBSTANTIALLY DRYING SAID IMAGE AND CONTACTING THE VISIBLE DRY IMAGE WITH A MOIST RECEIVER SHEET HAVING COATED THEREON A LAYER CONTAINING A MORDANT HAVING A STRONG AFFINITY OF SAID DYE SO THAT THE DYE IS THEREBY INSOLUBILIZED BEFORE WANDERING OF THE DYE CAN OCCUR.

Cl. 96--1.4 No Drawing. 13 Pages Specification A method of forming transferred liquid developed electrostatic images includes the steps of forming an electrostatic charge pattern on a charge-bearing member, applying to said pattern a liquid developer containing a mordantable, Water-soluble acid dye salt to form a developed image, substantially drying said image and contacting the visible dry image with a moist receiver sheet having coated thereon a layer containing a mordant having a strong affinity for said dye so that the dye is thereby insolubilized before wandering of the dye can occur.
